ABSTRACT
In this paper, we re-visit the issue of multi-point laser pointer interaction from a wrist-rolling perspective. Firstly, we proposed SLP---Structured Laser Pointer, and detects a laser pointer's rotation along its emitting axis. SLP adds the wrist-rolling gestures as a new interactive dimension to the conventional laser pointer interaction approach. We asked a group of users to perform certain tasks using SLP, and derived from test results a set of criteria to distinguish between incidental and intentional SLP rolling, and then the experimental results also approved the high accuracy and acceptable speed as well as throughput of such rolling interaction.
